10mm. (cris -n" I I H r plate; .theawebs having: aiign'edi openings? Ill The present invention relates to new and useful improvements in presses adapted for reshaping warped surfaces of metal plates, such as used in ship building and similar purposes, and the invention has for its primary object to provide upper and lower clamping plates between which the work is positioned, said clamping plates being formed of segments and providing means for the individual adjustment of each segment to provide an adjustable form within which the work is positioned for reshaping the same in a desired manner.

A further object is to provide an apparatus of this character of simple and practical construction, which is efiicient and reliable in performance, strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a vertical longitudinal sectional view.

Figure 2 is a vertical transverse sectional view.

Figure 3 is a horizontal sectional View taken substantially on a line 3-3 of Figure 1.

Figure 4 is a horizontal sectional view through one of the guide channels and rollers.

Figure 5 is a fragmentary sectional view through one of the adjustable ball and socket segments for the form, and

Figure 6 is a fragmentary side elevational view of the guide shoe for the base of the lower adjustable form.

Referring now to the drawings in detail, wherein for the purpose of illustration 1 have disclosed a preferred embodiment of the invention, the numeral 5 designates a plurality of spaced posts having their lower ends suitably anchored in the ground or other permanent structure, the posts being of channel shape in cross-section with the channel of each pair of posts disposed in opposed relation, as shown to advantage in Figure 3 of the drawings.

The upper ends of the posts are connected by beams 6, likewise of channel shape in crosssection.

An upper form is designated generally at I and includes a horizontal plate 8 supported beneath the beams 6 by vertically disposed spaced parallel webs 9, the webs 9 preferably being welded or otherwise suitably connected to the beams and formed therein.

Screws H are threaded through freely through a plate [2, disposed in spaced relation beneath the plate 8, the plate l2 being adjustable vertically with respect to the plate 8 and secured in adjusted position by means of nuts l3. The screws II are also adjustably secured in the plate 8. by means of nuts l4.

vThe edges of the plate l2 are provided with upper and lower rollers l5 and I6 journaled in brackets l1 and I8 secured to the plate, the rollers travelling along the edges of the channel-shaped posts 5.

Balls I9 are formed on the lower ends of the screws H, swivelly secured in sockets 20 by set screws 2!, the sockets 20 being formed on the upper surface of foot members 22, the foot members having substantially square surfaces, as shown to advantage in Figure 3 of the drawings, and with their edges disposed in close relation with respect to each other and cooperating to form an upper segmental plate for the form I.

A flexible lining 23 is secured to the lower surfaces of the foot members 22 by means of screws 24 and positioned between the lining 23 and the foot members 22 is a lining of insulation material 25, whichmay be of asbestos or the like.

A lower form is designated generally at 26 which includes a head plate 21 secured on the upper end of a hydraulically operated ram 28 by means of beams 29, the plate 21 having a plurality of horizontally-spaced upstanding webs 30 secured thereto for supporting a plate 3| on the upper edges of the webs, the webs preferably being secured to the plate of welding or the like.

Screws 32 are threaded upwardly through the plate 3| and freely through a top plate 33, the screws being secured in adjusted position by means of the nuts 34. and 35.

The screws 32 are constructed similarly to the screws II to provide the lower segmental clamping plates 36 on the upper ends of the screws 32 for cooperating with the upper segmental clamping plates as heretofore explained.

The plates 3| and 33 are provided attheir edges with the guide rollers 31 and 38 similar to the guide rollers for the plate I2and are adapted likewise to travel along the edges of the posts 5.

Rollers 39 are journaled in the posts 5 by means of pins 40 and bearings 4| and engaged with the rollers 39 are shoes 42 secured on the vertical sides of the head member 21.

In operation of the device, it will be apparent that the segmental upper and lower clamping the plate 8 and 7 detailed explanation,

Having thus descibed the invention what I claim is:

A press of the class described comprising plurality of posts, rollers journaled in said posts; an upper clamping member including a stationary plate, a, movable rigid plate and segmental clamping plate, screws connecting'the pla'testo' provide vertical adjustment of the movable plate relative to the stationary plate and for independent vertical adjustment, of the segmentsof the v rollers, and means connected to the base for movclamping plate relative to both the stationary plate and movable plates, rollers carried above and below the movable plate adapted to travel along the edges of the posts, a lower clamping member including a base, a plate fixed to the base, a movable rigid plate, and a segmental clamping plate, screws adjustably connecting the last-named segmental clamping plate to the lastnamed movable rigid plate and also connecting the last-named movable rigid plate to the lastnamed fixed plate, rollers carried above and below both the last-named movable plate and to the plate fixed to the base and adapted to travel along the edges of the posts, shoes carried by the base and adapted to travel over said first-named 'ing the lower clamping member in a manner to compress workagainst the upper clamping member.
